A new load-bearing insulation material made of cattail

Due to the special structural properties of cattail (typha) building materials can be produced offering a combination of insulation and strength, which is unique on the market. The leaf mass of typha is especially suited to produce innovative building materials due the structure of the plant. The leaves have a fiber-reinforced supporting tissue filled with soft open-cell spongy tissue providing for amazing statics and an excellent insulating effect. The newly developed magnesite-bound typha board has an extremely high strength and dynamic stability despite a low thermal conductivity of 0.055 W/mK and can solve energetic as well as static problems.
